Dinesh spent 85% of his salary and donated 10% for social work. If he is left with Rs. 1,250 at the month end, what is his salary ?
Let Dinesh's salary is Rs. x.
Then according to the problem, he spent 85% of his salary and donated 10% then remaining is 5%.
Then we have,
5x100=1,250
or, x=25,000.
So Dinesh's salary is Rs. 25,000.
